Washington: President Donald Trump on Wednesday pardoned disgraced media mogul Conrad Black, who served more than three years in prison in the US for fraud and obstruction of justice.

"In 2007, prosecutors alleged that Lord Black had committed several acts of mail fraud and obstruction. The Supreme Court of the United States, however, largely disagreed and overturned almost all charges in his case," the White House said in a statement announcing the pardon.

The statement described Black -- who wrote a book entitled "Donald J. Trump: A President Like No Other" -- as an "entrepreneur and scholar" who "has made tremendous contributions to business, as well as to political and historical thought."

His legal battles began in 2004 when he was accused of siphoning off tens of millions of dollars from the sale of newspapers owned by Hollinger International, his holding company.

Black, a prolific writer and historian in his own right, vehemently maintained his innocence and launched a series of libel lawsuits in Canada to strike back at the detractors he blames for destroying his once vast empire.

But years of legal battles -- which went all the way up to the US Supreme Court -- failed to fully clear his name, although he did manage to greatly reduce his prison time by clearing himself of many of the charges.

At its peak, Black's newspaper group was one of the largest media empires in the world, with revenues in the billions of dollars and global daily circulation in the millions.

As well as The Daily Telegraph in London, the group included the Chicago Sun-Times, Canada's National Post, and the Jerusalem Post.
